RADIATOR-VALVE.

SPECIFICATION forming part of Letters Patent No. 757,087, dated April12, 1904.

Application filed April 14, 1903.

To a/Z/ whom, t may concern:

Be itknown that I, ADoLrHUs L. Bowne, a citizen of the United States,residing at Lima, in the county of Allen and State of Ohio, haveinvented certain new and useful Improvements in Radiator-Valves, ofwhich the following is a specification.

This invention relates to valve attachments wherein communicationbetween the radiatorn hot-water systems and could not be employed` inconnection with steam-radiator systems.

The present invention has 1n view a single valve, which is equallyuseful for steam and hot-water systems, and can be readily convertedfrom one use to the other.

A further object of the invention is to provide a construction ofradiator-valve involving novel and eective means for draining back orreturning water of condensation in such a manner as not to oppose thesteam, besides maintaining ,a most effective circulation to insure theready and uniform heating of the radiator.

With theseand many other objects in view, which will more readily appearas the nature of the invention is better understood, the saine consistsin the novel construction, combination, and arrangement of parts, whichwill hereinafter be more fully described, illustrated, and claimed.

The essential features of the invention involved in the novelarrangement of the valveseat and the means employed for converting thevalve from one use vto the other are susceptible to structuralvariations without departing from the scope of the invention; but

Serial No. 152,497. (No model.)

a preferred embodiment thereof is shown in the accompanying drawings, inwhich- Figure l is an elevation of a portion of a jradiator of the steamor hot-water type, showing attached thereto a convertible valveembodying the present invention. Fig. 2 is an enlarged sectional view ofthe valve, showing the same open with the parts arranged for use with asteam-heating system. L ike reference numerals designate correspondingparts throughout both figures of the drawings.

In carrying out the invention no change is involved in the constructionof the radiator or in the pipe connections, so for illustrative purposesthere is shown in the drawings a few sections of a radiator, (designatedbythe numeral 1,) and which radiator may be of any approved type, suchas employed with eithersteam or hot-water heating systems whereincommunication between the radiator and boiler is controlled through themedium of a single valve. The single-valve controlling deviceconstitutes thepresentinvention and is of peculiar construction, asshown in the drawings.

Referring particularly to the drawings., the numeral 2 designates thevalve-casing as an entirety, and this casing is designed to have theusual pipe connections therewith-namely, a vsupply-nipple connection 3with the lower end of the iirst radiator-section and a rfeed-pipeconnection 4 with the boiler or pipe system connected with the boiler.To provide for proper coupling with the nipple and pipe connections 3and 4, the valve-casing 2 is formed with the right-angularly relatedinlet and outlet necks 5 and 6, which are respectively connected withthe pipes 4 and 3 and are dis-v posed in planes atV right angles to eachother. When the valve attachment is in its applied position, theinlet-neck 5 usually stands in a vertical plane, while the outlet-neck 6is disposed at the side of the casing-body and lies in a horizontalplane.

In addition to the right-angularly related inlet and outlet necks 5 and6 the casing-body 2 is formed with an upstanding valve-chamber 7,projecting above the planes of both of the necks and disposed obliquelythereto. In

the preferable construction the inclined upstanding valve-chamber isdisposed at an obtuse angle to the inlet-neck 5 and at an acute angle tothe outlet-neck 6, and the same is designed to accommodate therein theimperforate cut-0H valve-disk 8, carried by the inner end of thevalve-stem 9, adjustably mounted in any approved way and extendingthrough the stuiing-box cap 10, fitted over the outer end of thevalve-chamber 7, said stem 9 carrying upon its outer end exterior to thevalvechamber the usual operating hand-wheel 11.

By reason of the disposition of the inclined oroblique valve-chamber 7the valve-stem 9 is held to work in an inclined plane and the interiorcut-off valve-disk 8 playsover the interior inclined valve-seat 12.

The valve-seat 12 is produced by an integral annular flange formedwithin the body of the casing at the inner end of the inlet-neck 5 andforms thereabout an annular drain-gutter 13, the lowest point 14 ofwhich is disposed the greatest distance from the outletneck 6 and liesin a plane below the horizontal plane of such outlet-neck. It will beobserved that the flange-like valve-seat 12 lies in a plane at rightangles to the plane of movement of the cut-off valve, and hence is setoblique to the planes of both the inlet and the outlet necks and at thehighest point in the gutter 13, surrounding the valve-seat, and hence ata point nearest to the valve-neck 6 the valveseat web of thevalve-casing is provided with an auxiliary heating-vent 15, adapted tobe temporarily closed by a closure-plug 16, usually in the form of anordinary headed screw, which is readily accessible for removing andreplacing through the inlet-neck 5.

When the valve is employed in connection with a steam-radiator, the vent15 is closed by the plug or screw 16, and by reason of the peculiardisposition of the valve-seat 12 and the drain-gutter 13 it will beobserved that the steam is caused to enter the valve-casing in such away as to move ltoward the top thereof before being defiected into theradiator, and hence entirely out of contact with the water ofcondensation, which may be returned into the valve-casing. Such waterpasses from the lower side of the outlet-neck 6 into the annular gutter13 and overfiows from the lowermost point 14 of such gutter over thelowcrmost edge of the valve-seat 12 and thence back into the pipe ithrough the neck 5.

When the valve is employed in connection with a hotwater heating system,it is .only necessary to remove the plug or screw 16, so that when thecut-olf valve 8 is closed on its seat a sufficient circulation of hotWater will be maintained through the auxiliary vent 15 to provide forkeeping the water warm in the nipple connection leading from thevalve-casing to the radiator.

From the foregoing it is thought that the construction, use, and manyadvantages of the herein-described radiator-valve will be readilyapparent without further description, and it will be also understoodthat changes in the form, proportion, and minor details of constructionmay be resorted to without departing from the spirit of the invention orsacrificing any of the advantages thereof.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

A combined hot-water and steam-radiator valve comprising a valve-casinghaving angularly-related inlet and outlet necks and provided at theinner end of the inlet-neck with an inclined valve-seat flange setoblique to the planes of both of said necks, and forming thereabout anangular drain-gutter, the lowest point of which gutter is below theplane of the inner side of the outlet-neck, said valvecasing beingfurther provided with an auxiliary heating-vent piercing the valve-seatweb in the highest point of the gutter at one side of the face of thevalve-seatat a point near to the outlet-neck, a temporary removableclosure-plug fitted in said vent and exposed for manipulation throughthe inlet-neck, and a cut-off valve-disk arranged over the obliquevalve-seat.

In testimony whereof I affix my signature in presence of two witnesses.
